Effect of Heat Moisture Treatment Combined with Sodium Alginate on Physicochemical Properties of Normal Corn Starch
摘要
Abstract
The effects of heat moisture treatment (HMT) combined with sodium alginate (AG) on pasting properties,thermal properties,crystalline structures,and gel properties of normal corn starch (NCS) were investigated.NCS was subjected to HMT alone or in combination with AG (HMT-AG) under the following conditions:moisture content of 15％-35％,temperature of 80-120 ℃,and time of 1-15 h.The results showed that HMT-AG increased the pasting temperature of NCS,but significantly decreased its breakdown value,setback value,and gelatinization enthalpy (P ＜ 0.05).Either treatment did not change the crystalline pattern of NCS.At moisture content above 25％ (P ＜ 0.05),HMT obviously decreased the relative crystallinity (RC) of NCS (P ＜ 0.05) whereas the opposite was observe with HMT-AG.Under the conditions of moisture content of 25％,temperature of 120 ℃,and time of 6 h,HMT-AG resulted in more significant decreases in the viscosity,gelatinization onset temperature,and gel hardness of NCS compared to HMT alone (P ＜ 0.05).关键词
